Rice crops are grown in all regions of the country, Thailand, but still found a significant problem that damage rice production greatly. Specifically, the blight epidemic found in abundance in the North East of the country, Thailand, which is mostly na relies on rainwater. Rice breeding is resistant to blight, so as to help reduce the risk of loss of rice production caused by the outbreak of the powerful burns. In this research, make the bringing of rice through breeding blight resistance breeding is grain to serene in comparison with rice kdml 105 which is a species that is susceptible to disease. Two rice varieties which have the same characteristics, genetic base. By bringing the two rice varieties planted in the trials, divided into 2 and 5 are converted in convert by value, score level for the disease in all three times after the move grows at 30, 40 and 50 days after planting. Tillers term until full term including tillers, neck, comb and collect information concerning agriculture include height. The tillers Length of tree weight weight weight all the haggling, the seeds and the size of the seed, which collect and keep up with the disease. When analyzing data, found that the rice grain, Sirin, disease resistance are higher. Rice kdml 105 section characteristics of various agricultural products remains the same as white rice Jasmine 105, so the rice grain Sirin chuek fits in to grow in areas with outbreak of leaf burning efficiently.
